Final answer:
The idea that work purposes can be classified as economic, social, and psychological comes from the collective work of various sociologists, philosophers, and psychologists. Notably, Adam Smith, Frederick Taylor, and Elton Mayo explored different dimensions of work and its implications for individuals and society.
Step-by-step explanation:
The individual who suggested that the purposes of work can be classified as economic, social, and psychological was not directly mentioned in the provided references. However, we do see a broad spectrum of scholars and thinkers like Adam Smith, Karl Marx, Max Weber, Frederick Taylor, and Elton Mayo who have contributed to the understanding of work from multiple perspectives including its functional, economic, and socio-psychological dimensions.
Thus, the roots of this idea can be credited to the collective work of these sociologists, philosophers, and psychologists. For instance, Adam Smith was concerned with the impact of specialization in work on the meaningfulness of labor, Frederick Taylor emphasized improving economic efficiency and worker wages through scientific management, and Elton Mayo's Hawthorne studies highlighted the importance of psychological and social factors in productivity and work satisfaction.
In the related field of industrial and organizational psychology, influential psychologists like James Cattell and Kurt Lewin explored aspects of industrial efficiency, employee selection and training, as well as leadership styles and group dynamics, contributing to a richer understanding of work from an economic, social, and psychological view.
